Habitat.—Near the entrance to Holm Sound; rather 
rare. 
The only other Scottish localities I know of where 
this species has been observed are the Firth of Forth 
and the Moray Firth. 
In preparing these notes I have consulted the 
Monograph of the Recent British Ostracoda (1868), by 
Dr. G. S. Brady, and the Monograph of the Marine 
and Fresh-water Ostracoda of the North Atlantic 
and North-western Europe (1889) by Drs. Brady and 
Norman. Iam also much indebted to my kind friend 
Dr. G. S. Brady, who has on this and many other — 
occasions assisted me by looking over my collections 
and identifying obscure and difficult species.
